Eliminating error in the chemical abundance scale for extragalactic H ii regions

Lopez-Sanchez, A R; Dopita, Michael; Kewley, Lisa J; Zahid, H J; Nicholls , David; Scharwaechter, Julia

Description

In an attempt to remove the systematic errors which have plagued the calibration of the Hii region abundance sequence, we have theoretically modelled the extragalactic Hii region sequence. We then used the theoretical spectra so generated in a double-blind experiment to recover the chemical abundances using both the classical electron temperature + ionization correction factor technique and the technique which depends on the use of strong emission lines (SELs) in the nebular spectrum to...[Show more]
